CARPENTERS GAGE.

SPECIFICATION forming part of Letters Patent No. 569,739, dated October20, 1896.

Application tiled February 29, 1896. Serial No. 581,374. (No model.)

To @ZZ whom, it may concer/1,.-

Be it known that I, RICHARD BATES, a citizen of the United States,residing at Bloomsburg, in the county of Columbia and State ofPennsylvania, have invented a new and useful Carpenters Gage, of whichthe following is a specification.

rlhis invention rela-tes to an improvement in carpenters gages, and theobject in View is to provide a convenient and efficient gage which iscapable of being used either upon the inside or outside of a circle oragainst a beveled edge, and which is also adjustable to circles ofdifferent sizes and to bevels of diderent pitch.

To this end the invention consists in an improved gage embodying certainno vel features and details of construction and arrangement of parts, ashereinafter fully described, illustrated in the drawings, and finallypointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view showing theimproved gage applied to a gage-stick. Fig. 2 is a side elevation of thesame. Fig. 3 is a plan view thereof. Fig. 4 is a reverse plan viewthereof. Fig. 5 is a front end View of the same. Fig. G is alongitudinal section through the same with the gage-stick in elevation.Fig. 7 is a detail perspective view of the slide.

Silnilarnumerals of reference designate corresponding parts in theseveral gures of the drawings.

Referring to the accompanying drawings, 1 designates the usualgage-stick, provided at one end with markers 2, arranged upon andprojecting from opposite sides thereof. 3 indicates the frame of thegage, which in the present instance is in the form of an approximatelysquare sleeve, such sleeve being made to correspond in itscross-sectional shape to the gage-stick and being sufficiently loose toslide longitudinally of the stick.

The frame 3 is extended laterally upon opposite sides to form lugs e,the extremities of which are rounded to form smooth working faces andextended in parallel relation beneath or beyond one face of thegage-stick, as clearly shown in Fig. 5. For the purpose of strengtheningthe lugs a horizontal webs 5 connect the same with the frame 3, as shownin Fig. e.

G designates an adjustable slide in the form of a short fiat har, havingat its extremities and upon the same side thereof a large gagelug 7 anda small stop-lug S. This slide is mounted to reciprocate in a groove 9in the inside of the frame and may be xed at any point of adjustment bymeans of a thumbscrew lO, which passes through the frame and presses theslide (i against the gage-stick. The frame is also formed with alongitudinal open slot il, into which the small stop-lug S maybe movedwhen the gage-lug 7 is moved forward beyond the plane of the laterallugs 4L. The slot thus provides for the greater adjustment of the slide,and the stop-lug prevents the entire withdrawal or accidental escape ofthe slide. Itull thus be observed that three bearing-points are providedfor adapting the gage to be used in connection with curved edges orsurfaces, and by means of the adjustment of the gage-slide 6 the gage asa whole may be adapted to a circle of any size, and so that it may beused either upon the outside or inside of the circle, as indicated inFig. e.

One of the principal advantages of having the intermediate adjustablegage-lug resides in the fact that the gage as a Whole will be properlysupported to the extreme edge of the Work, whereas if said intermediatelug were absent as soon as the edge of the Work was reached one of thelateral lugs el Would slip from the end of the board or other Workbefore the marker had reached such end. The intermediate lug effectivelyovercomes this difficulty.

Upon the reverse side of the frame, or that side which is shown asuppermost in the drawings, is mounted a pivoted gage-plate 12. Thisplate is substantially U-shaped and extends around three sides of thefram e. It is pivoted to the frame by means of a transverse pin 13,passing through spaced ears 14E on the rear side of the gage-plate l2,and also through a lug on the frame. At its outer or top edge the platel2 has spaced ears 15, between Which is received pivotally the forwardend of a segmental strap 16, by which the angle of the plate may be adjusted. This segmental strap is formed Wit-h a longitudinal slot 17,through which passes the threaded shank of a thumbscrew 18, the samescrewing into the frame IOO of the gage. By loosening the thumbwscrew 1Sthe segmental strap is free to move longitudinally and the plate l2 maythereafter be adjusted to the desired angle With relation to theadjacent face of the gage G. The plate l2 may be adjusted to a positionexactly at right angles to the gage f5 by bringing the bifurcatedportions of the plate at their extremities into engagement with the webs5 of the frame, such Webs being formed with rah? bets 19 for thereception of such extremities and so disposed that when the parts are inthe position just referred to the gage-plate l2 will be at a preciseright angle to the gagestick, thus adapting the device to be used upon asquare edge as well as a beveled edge.

From the foregoing description it will be seen that a very convenientand efficient gage for carpenters7 use is obtained, the utility of whichis greatly increased by the fact that the gage may be used either uponinside or outside curves or upon beveled' edges, and the further factthat it may be regulated to suit the curve of any radius or a bevel ofany pitch.

It will also be apparent that the gage will be supported to the extremelimit of the Work, and that the marker will be correspondinglysupported.

Changes in the form, proportion, and minor details of construction maybe resorted to Without departing from the spirit or sacrificing any 0fthe advantages of this invention.

Having thus described the invention, what is claimed as new isl. Thecombination with a gage-stick, of a longitudinally-adjustable gageadapted for use upon curved surfaces the same comprising spacedgage-lugs rigid on the gage-frame, and an intermediate adjustablegage-lu g, substantially as and for the purpose described.

2. A carpenters gage for use on curved edges or surfaces, comprising agage-stick, a gage-frame slidingly mounted thereon,spaccd gage-lugscarried thereby, a longitudinallyadjustable slide located intermediatesaid lugs and also carried by the gage-frame, a gageslug on the saidslide and adjustable therewith, and means for adjusting and holding theslide, substantially as specified.

The combination with the gage-stick, of the sliding gage-frame providedwith a longitudinal slot opening out at one end thereof, spacedgage-lugs having a rigid relation to said frame and located uponopposite sides of the gage-stick, an adjustable slide capable oflongitudinal movement With relation to the gage-frame and carrying atone end an intermediate gagelug and at the other end a stoplu g Workingwithin the slot in the gage-frame, and provision for holding the slidefixed, substantially as described.

4. A gage comprising a suitable head or frame having three gage-lugs,the intermedi ate lug being adjustable in a plane substantially at rightangles to a line drawn through the other lugs, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto atlixedmy signature in the presence of two witnesses.
